The position of the member C, after being driven into position, is indicated in Fig. 4.. When the member 0 hasbeen driven into position, the member D is placed with the surface L engaging with the surface H of the member 0 and rotated about the member C until the. arm-O comes into contact with-the upper edge of the rail, as illustrated in Fig. 4. The member D is then and moves first angularly about the member C with surfaces L and H coactin and, in so doing, a vertical pressure or pu l'is exerted u on the member C, the first'efiect of which is to deflect the camber-ed or curved portion G and'bringit into contact with and to cause it to exert ressureupon the bottom-of the rail base. Rhis action distributes the pressure of C upon the bottom of the .rail, so that all of the contacting portions of C are pressin upwar upon the rail with pressures etermined by'the elastic strength of the matethe member C is constructed ber D. At'the same time,

I ass. result of this forced angular'movement of the member D,

a transverse pull is also exerted by D .upon C so that the pressure of the contacting surface P with the edge of the rail is increased; This transverse or horizontal ressure or pull, is relatively large during tliat portion of bout 0, in which the e movement of Da surfaces L of D and H .of G coact. As the forced angular movement of D is continued, the engagement of D. with C asses from -,'.contact of the surfaces L and to contactof the surfaces M and I, as illustrated in Fig. 5, .with a corresponding change in the characterfloi the pressure or pull exerted b D upon Gfthe transverse or horizontal pu l becoming relatively less and the vertical pressure or pull relatively more. Durin the further movement necessary-to force into place, the surfaces Mand I coact and cause D, while exerting some transverse or horizontal pressure, to produce a relatively large vertical pressur the efi'ectof whichher C and the part D and 1s to draw the end of C firmly against the bottom of the rail causing the arts C and to; clamp the 'rail fbase rigit ly between them. With the artsfin operative'position as illustrated in l ligsi 1 and 2, one side o the rail base is clamped between the portions E and F of'the member C, the other sideof the rail base is clamped between the memthe member 0 is pressing u wardly with a pressure whi h ]S distribute across the bottom of. the rail base. The rail base is thus veryfirmly ipped by the device and the engagement of t e portion K of the artC with the tie B, which is firmly held by the ballast and earth in which it is embedded, effectual] prevents longitudinal movement of the rai 'A somewhat difi'erent form of construction is disclosed in Figs. 6, 7, 8 and 9. In this embodiment of the invention the flange gripping member C is provided with spaced portlons E engaging. with the up or surface of the rail base and a portion lying between and below the portions E engaging with the bottom of the rail base. The end of the member 0, opposite to the portions E and F, is constructed with a convex surface H and a concave surface I. The part C is'curved or cambered as indicated at G and provided with duplicate tie engaging portions K. The vertical pressure producingmember, in this embodiment, differs from that described above only so far. as is necessary to adapt this part to be used with the part C. .It is provided with surfaces L and M complementary to the surfaces H" and I of the part C; and, in being forced into position, moves angularly'with-the surfaces H and L coacting inthe early movement and the surfaces I and M coaeting in the later movement ofthe part D. It will be obvious that the device operates in substantially the same manner as that firstdescribed, in so far as the application of the parts and the clamping or ipping of the rail to revent creeping is e ected.

It wi 1 be noted that, in each form of con-' 9 struction above described, the

is in then'ature of derstood that various changes in the size,

shape, proportion and minor details of construction may be resorted t without departing from the spirit or sacrificing anyof'the 1 I advantages. of the invention.
